The paper considers the issue of finding the optimal angle of penetration of the bucket into the rock in a hydraulic excavator. The study was carried out using 3D modeling and simulation technology using Autodesk Inventor software. For this, a model of the working body of the excavator was created, on which the calculations were made. The final result of the study was graphical dependencies, which show the change in the angle of penetration of the bucket from the angles of deflection of the working boom, which allows us to conclude about a rational angle of deflection at which it is possible to reduce the working cycle of the excavator. Given the human factor and the incomplete autonomy of the excavator's working cycle, this study is more applicable to automated excavation, which the modern engineering community is striving for.
